MACHINE FOR POLISHING NEEDLES AND THE LIKE.

Application led January 6, 1916.

Togli whom t may concern.' Y

Be it known that I, CHARLEs Eiuvnsr Bain Lis, a subject of the King of Great Britain, residing at Redditch, in the county of lVorcester, England, have invented certain newV and useful Improvements in Machines for Polishing Needles and the like, of which thefollowing is a specification.

Myjinvention relates to the process of polishing or scouring needles, knitting pins and 'other cylindrical or otherwise shaped wires or shafts and consists of the improvements hereinafter described in the machinery employed in carrying the process into effect.

In order that my invention may be the better understood I remark that in the process of polishing or scouring needles and the like as commonly practised the said needles are wrapped in harden and are thereby made into bundles or packets the polishing material, emery or the like and oil or other liquid, being freely distributed on the needles in making up the packets or bundles; the said packets are then subjected to pressure and slight motion so as to cause the needlestherein to move against and knead the adjacent needles or shafts. Various maehines have been devised for subjecting the packets or bundles of needles to pressure and motion.

The new or improved machinery constituting my invention comprises a set or series of resilient or flexible rollers, that is to say, rollers the acting surfaces of some or :all of which are capable, under the restraint -of spring pressure, of yielding or partaking of a limited movement with respect to their aXes and to the packet of needles or the like under treatment, the rollers, when in operation, by virture of the resiliency or iiexibility referred to effecting a very efficient kneading action on the packet or bundle of needles or the like.

I will further describe my new or` improved machine with reference to the accompanying drawings Figure l of which represents in front elevation, partly in section, one end of the machine with a bundle or packet of needles under operation therein; Fig. 2 is an end elevation of the machine and Fig. 3 is a cross section throughone of the rollers of the machine. Figs. 4, 5 and 6 illustrate a modified construction and arrangement hereinafter particularlydescribed Specification of Letters Patent. i

for obtaining the requisite resiliency in the rollers of the machine.

The same letters of reference indicate the same parts in the several figures of the drawings.

I will first describe the arrangement Figs. l, 2 and 3. a, ct, a are resilient rollers each made preferably of two semi-cylindrical or vfha'lf tubular parts boltedtogether by the screw bolts Z2, b as is best seen in Fig. 8.11

Secured to the interior of each half tube, when the same is made of wood, is a metallic bar c the spaces between the fiat faces of the bars c, c when the two halves of thc rollers a, are secured together accommodat! ing the axial shaft or spindle CZ of the roller whichshaft Z is of a square ligure inA cross section. The spaces between the sides of the square shaft CZ not presented to the metallic bars c andthe interior of the rollers t are filled with India rubber e; or coiled springs, inflated tubes or other spring cushions may be arranged in the said spaces. The ends of the square shafts Z preferably run on the coned ends of spindles f so as there-` by to reduceI friction to a minimum when the machine is at work. The axes of two rollers a. are in the same horizontal plane and are stationary,'but the spindles of the other or upper roller a are carried by collars g working on tubular uprights or standards it, the collars being seated on coiled springs c', or other elastic supports, and from the spindles f ofthe upper `roller a a platform if; is suspended. On the said platform Z3 weights (not shown) are placed so as to obtain the desired pressure on the bundle or packet Z of .needles or the like under treatment, or the pressure on the upper roller a A`may be otherwise obtained. By the construction of the rollers ar hereinbefore described and illustrated they possess considerable resiliency, and this resiliency of the rollers in conjunction with the vertical movement which the upper roller a is capable of, due to the elastic support of the 'collars g carrying the spindles f and the loaded platform 7c, insures such a kneading action on the packet or bundle Z, when the machine is at work, that a very eflicient and expeditious scouring and polishing of the inclosed'needles 'resultsn The two lower rollers a, a are #driven vby a` chain or chains (not shown) :gearing with a sprocket wheel or sprocket wheelena ontlie square spindles l and with sprocket wheels -on a driving shaft (not shown). rIhe upper roller a rotates under the action of the bundle or packet of needles Z which is contacting with the three rollers a, a., a. Means are or may be provided for taking the weight of the loaded platform 7c 0E the upper roller a when the spring supports 'Z will raise the said roller off the packet or bundle Z and the said bundle or packet Z can be readily taken out or lifted from its position on the lower rollers a and deposited in a concave trough 'n to receive necessary treatment at the hands of the operator while at the same time another packet or bundle is placed on to the lower rollers to be subjected to treatment in the machine and thereby lthe machine is kept practically in continuous operation and loss of time is obviated. A series of the said machines are preferably arranged side by side or end to end all driven by the same driving shaft which is arranged under the machines and may be readily concealed if desired and the driving shaft is or may be furnished with a fly Wheel and a three speed reversible gear so as to provide for varying the spe-ed to suit the work under operation.

In the modified arrangement represented in end elevation in Fig. 4 and in front elevation (partly in section) in Fig. 5 I have represented a series of three machines side by side three upper rollers a being used in combination with four lower rollers a, but

I wish it to be understood that the said modified arrangement is equally applicable to a single machine. The rollers in this machine are represented as complete rollers, that is to say, they are not composed of sections, as are the rollers shown in Figs. 1 to 3.

. Further, the upper rollers a have' no resiliency except that which results from the suspension of the spindles on springs or elastic supports which permit slight vertical movement of the said spindles. Ball bearings are provided between the upper rollers and their spindles. The lower rollers a are provided with crossing pins p, r near each end the said pins passing through the square spindle d. The pins p have on them coiled springs s and the pins 1' carry rubber buffers t which springs s and buffers t impart to the rollers a the requisite resilencyk to insure the l proper kneading action on the bundles or packets of needles or the like introduced into the machine. The upper rollers a also have a yieldable movement to and from the lower rollers a and the means for permitting such a movement of the upper rollers a in Fig. 4 consists of pairs of uprights 3 spaced relative to each other to provide guide-ways in which the spindles f of the upper rollers a move. Each pair of uprights 3 are connected by the cap member 2 which bridges the upper end of the guide-way and from each depends a retractilJ spring z, one

being connected to each end of the rollers to support them in guide-ways. The upper ends of the retractile spring e are secured tol of the upper roller a (at'each end thereof) by the cables u which engage with the hooks z/ passing through the spindles. The rod 'u is connected with the base of the machine or to the floor by the retractile springs rw and the angle irons a', the latter being immediately secured to the base of the machine or to the floor. It will thus be seenthat the upper rollers a are constantly under yieldable tension, which latter is exerted upon the package of needles or the like between the lower and upper rollers for treatment. By rotating the screw nuts 4 on the screws l the tension of the springs w, e may be adjusted with great nicety. The tubular uprights 3 are secured in cored holes in the end parts 9 of the frame of the machine by short middle tubes 5 driven down between the tubes 3, 3 as is best seen in the horizontal section Fig. 6 of a portion of one of the end parts 9 of the frame. One pair of lower rollers a is driven by a chain 6 gearing with a sprocket wheel on the driving shaft 7 and the other pair of lower rollers a is driven by another chain 8 gearing with a sprocket wheel on the other end of the driving shaft 7. In other respects the machine illustrated in Figs. 4 and 5 resembles the single machine hereinbefore described with reference to Figs. l, 2 and 3.

Although in the compound machine illustrated in Figs. 4 and 5 I have represented an arrangement for simultaneously operating on three packets or bundles of needles or the like I Wish it to be understood that by increasing the number of rollers more than three bundles can be accommodated.

By the construction and arrangement or combination of parts hereinbefore described and illustrated constituting my new or improved scouring or polishing machines the following among other advantages are obtained:-There is great saving of power, friction from end thrust is practically eliminated, the machine can be run at a high speed and a very efficient kneading action is thereby obtained considerably reducing the time of polishing or scouring process; fur ther, the machine is capable of taking or accommodating packets or bundles of varying length and bulk and the parts which are few and easily accessible can be readily separated for cleaning or other purpose.

Having now described my invention what I claim as new and desire to secure by Letters Patent is 1. In a machine for polishing needles or like articles, a plurality of rollers arranged `relative to each other to have packages of needles introduced and retained therebetween so as to be acted upon by said rollers, the acting surfaces of certain of said rollers being adapted to have a radial movement relative to the axes thereof.

2. ln a machine for polishing needles and like articles, two rollers arranged substantially parallel to support a package of needles or the like while under treatment, the acting surfaces of the rollers being yieldable to pressure, a pressure roller hav` ing its aXis yieldingly movable relative to the first-mentioned rollers and arranged to bear upon the package supported upon the latter, and means for driving said rollers.

3. In a machine for polishing needles or like articles, a plurality of rollers arranged to receive and retain a package of needles therebetween, a frame, shafts journaled in the frame on which said rollers are mounted, means interposed between said shafts and rollers for permitting the latter to have a radial movement relative to the shafts at certain points of their circumference, where` by a kneading operation of the rollers upon the package is obtained, and means for rotating said rollers.

4. A machine for polishing needles or the like comprising two rollers arranged in coopes of this operative relation and having the axes thereof stationary, the acting surfaces of said rollers being movable relative to their axes, a pressure roller arranged in coperative relation with said driven rollers and having its axis yieldably movable relative to the axes of the latter, whereby a kneading operation of the rollers is obtained, tension means controlling the movement of said pressure roller, and means for rotating said rollers.

A machine for polishing needles or like articles comprising two driven rollers having stationary axes, means embodied in said rollers for permitting the acting surfaces thereof to have a movement radially of their axes, a. third pressure roller having its aXis capable of movement relative to the axes of said first-mentioned rollers, means for placing the pressure roller under tension, and standards for guiding the pressure roller in its motion toward and from the other rollers.

In testimony whereof I have hereunto Set my hand in presence of two subscribing witnesses.
